The present invention relates to'improvements in vehicle wheels and has for an ob ect fvlhich bears against the brakedrum or the 5 i e. l

' The invention further aims to provide interlocking teeth between the wheel and the hub, such teeth being held in mesh under elastic pressure which is controlled by a threaded hub or screw cap.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out. in the claims appended hereto. y

the

Referring more particularly to Figure 1, A-

represents a disk wheel and M the hub on which this wheel is mounted. The hub carries a brake drum T against which the disk wheel A bears as at the point indicated at B.

Figure 1 is a vertical section taken through i around the tee The disk bears annularly all about the drum T. The central part of the disk A is rounded to provide an improved removable wheel and carried inwardly along the hub M to form a cylindrical bearing part N. Riveted or otherwise secured to this part N is a reinforcilg bearing cylinder P. Opposed to this cylin er P, which fits upon the hub M, is an elastic or resilient member C fixed at R to the brake drum T, and embodying in its construction preferably a series of curves in order to impart the desired resiliency. The members may be made of appropriate metal.

Teeth of trapezoidal or other form D and Q are provided upon the members C and. P, which teeth are adapted to intermesh, as indicated in Figure 2; Owing to the elasticity' of the member C, the teeth are resiliently held in mesh. There is a screw cap or hub cap E threaded upon the outer threaded portion of the hub M which functions to bind the disk wheel upon the hub and incidentally may be screwed up tightly to place the member 0 under appropriate tension whereby the teeth are bound more tightly'together. Also the disk A will bear very tightly at B upon the brake drum and thus the'disk wheel will be placed under proper tension and willbe may be readily removed and reapplied by simply one fastening means E.

-An annular 'art or ring F may be placed th I) and Q to prevent foreign matter from entering between such teeth during the movement of the vehicle.

In Figure 1 theelasticity is'secured from the member 0. a

In Figure 3 however the elastic member C reverse loops in order to impart the necessary I resiliency and it carries the teeth Q, trapezoidal or of other form, which engage the similar and complemental teeth D carriedby the hub M or by the brake drum T. The 9 elasticity in this case is given bythe part C- under the action of the screw or hub cap E.

The shape of the teeth may be optional. '7

A few desirable shapes are indicated in Fig ures 4, 5 and 6. Figures fi and 6 show teeth' brake drum T.

stampe with inclined faces while Figure 5 shows teeth with parallel faces.

Referring to Fi fixed to the brake drum .T as indicated at R. The disk wheel A has secured to it by rivets or otherwise a cylindrical piece P, and teeth D andfQ' are provided between the members C and P being covered by a ring F if desired. If desired, the part P of the wheel carrying the teeth also possesses a certain elasticity. The locking screw or-hub cap E maybe provided with a lock to prevent the unauthorized removal thereof.

Referring to Figure 8, the invention is shown as applied to a wooden wheel or a wheel other than a disk wheel. The wooden wheel is shown at U and it'is carried upon the hub M being held thereto by a hub cap K. The elastic member 0' is fixed to the brake drum T, as indicated at R. Teeth D are made between the member C and the wheel U, the wheel being ap lied against a conical annular surface G o the -brake drum. In this case also, the teeth D are held in an elastic manner.

In Figure 9, a wheel having metal spokes 10 is shown. This wheel carnes an annular or cylindrical part P having teeth which engage with the teeth of the resilient member C which is ailixed to the brake drum T.

beTl; wheel is held in place by the mem- In Figure 10, a modification is shown in which the elastic member C is formed in one piece with the brake drum T.

In Figure 11, a further modification is shown in which the disk wheel A itself forms the elastic member and carries the teeth which mesh with the teeth upon the hub M or the .brake drum T.

Referring to Figure 12, this also shows a wheel inwhich the wire spokes 11 are employed, including the toothed members P and C, the latter member being afiixed to the Referring to Fi ures 13 and 14, there is shown a metallic w eel in which the disk A is provided with a cylindrical member P having teeth for meshing with similar teeth upon the elastic member C aflixed to the brake drum P.

In Fiigure 14, the spokes Z are shown to be in the outer part of the disk A, the

central part being preferably imperforate. The length of the spokes Z is optional. Although the various forms of the invention include a central locking screw or hub cap it will-be a parent that many other modes 0 attaching t e wheels to the hubs may beused. The elastic part may be carried by the wheel, by the hub or by both at the same time.

By the use of the device, the gear teeth are constantly maintained in mesh and the motion of the axle is taken up without play by re 7,- a modification is here shown in which the elastic part C is the wheel. The mounting and demounting is effected in a sure and rapid manner.

It will be obvious that various changes in the construction, combination and arrangement of lparts could be made, which could be used wit out de arting from the spirit of my invention, and do not mean to limit the invention to such details, except as particularl pointed out in the claims.

avin' thus described my invention, what I c aim and desire to secure by Letters Patent of the United States is:

1. In a vehicle wheel construction, a vehihaving teeth, a hub for demountably receiv ing said wheel, a brake drum, a curved member secured to the brake drum and having teeth to detachably mesh with the teeth of the wheel, a protecting means extending about said intermeshing teeth, and a screw cap on the hub bearing ing the wheel a ing the teeth in mesh and placing said elastic member. under tension.
